CARD-CUTTING MACHINE.

To all whom it may concern:

Be it known that I, JOIIANN JACOB Kmioirr, a citizen of Switzerland, and residing at Chemnitz, Saxony, Germany, have invented certain new and useful Improvements in Card-Cutting Machines, of which the following is a specification.

My invention relates to card-cutting machines, and a primary object is to provide a new card-cutting machine for automatically-operated embroidering machines. In my new machine the punches are mounted in two parallel drums or cylinders and can be driven into cards passed between the drums.

One illustrative embodiment of my invention is represented by way of example in the accompanying drawings, wherein Figures 1 and 2 are diagrammatic side and front elevations, respectively, Figs. 3 and 4 developments of parts of the two revoluble drums, Figs. 5 and 6 vertical longitudinal section and transverse section, respectively, through the two superposed revoluble drums on an enlarged scale, and Figs. 7 and 8 show in elevation and top plan view, respectively, and likewise on an enlarged scale means enabling the card-cutting mechanism to be automatically disengaged after it operates each time.

Referring to the drawing, 1 designates the pattern according to which the cards are to be cut, 2 the pattern board, and 3 the pantograph pin movable readily in two guides 4, 5 at right angles to one another. These guides are respectively secured to or integral with slides 6 and 7 movable parallel to one another in the brackets 8, 9 and 10, 11, respectively. These slides are formed as racks and are balanced by counterweights, not shown, suspended respectively from cords 15 and 16 running over pulleys 13, 14,

respectively. When pin 3 moves the two slides are moved up or down, but obviously the motion of the two slides may be derived from the embroidery frame of an embroidering machine.

Shafts 22, 23 are journaled in the pedestals 20, 21. Drum 24 is free to rotate on shaft 22 and drum 25 on shaft 23. Gear wheel 26 is firmly connected with drum 24 and gear wheel 27 with drum 25. 26 can be actuated by the toothing of slide 7 with the intermediary of pinion 28 and gear wheel 29, and wheel 27 can likewise be Specification of Letters Patent.

actuated by the toothing of slide 6 with the intermediary of pinion 30 and gear wheel 31.

On shaft 22 is secured gear wheel 32 which meshes with pinion 33 revoluble on shaft 34 fixed in the frame. With wheel 33 is rigidly connected the axially non-displaceable part 35 of a clutch-coupling with which the claws 36 of the part 37 axially displaceable on shaft 34 can be brought into engagement. The driving pulley 39 is secured on the part 37 of the clutch.

On shaft 22 is secured sprocket wheel 40 by which the rotation of shaft 22 is imparted with the intermediary of chain 41 to the sprocket wheel 42 secured on shaft 23.

Between the two cylinders or drums 24, 25 I arrange two plates 43, 44 having pe1' forations 45, 46, respectively. Within the drums I arrange in rows and radially movable punches 47, 48 guided in the walls thereof.

As the developments of parts of the drums 24, 25 illustrated in Figs. 3 and 4, respectively, clearly show, the punches are arranged in groups in the rows a, Z), 0, (Z, c Row av contains groups A, each of which comprises only one punch; row Z) contains groups B, each of which consists of two punches; row 0 contains groups C, each of which consists of four punches; row (Z contains groups D, each of which consists of eight punches, and so on. From this it is clear that the groups A, B, C are to each other with respect to the number of punches forming each group as the members of a geometrical series, 2'. e. as 1 2 4 8 16 and so on. The resultant values of all the punches in each horizontal row a, b, c, d, c, f, g, h, i, is, Z, m, n are to one another with respect to the displacement of the embroidery frame as the members of an arithmetical series 71. e. as 1 2 3 4 5 6 :7 :8 :9:10 :11 :12 :13andsoon. Namely, all the holes which are punched by the punches of the vertical row a have the 1 value 1, since the smallest motion can be imparted by the card to the embroidery frame by the holes of this vertical row a, the holes which are out by the punches of the vertical row 5 have the value 2, those cut by the punches of the vertical row a the value 4, those out by the punches of the vertical row d the value 8, those out by the punches of the vertical row a the value 16, and so on. But on the horizontal row a is only one punch, which is located on the vertical row a and consequently has the value 1; the horizontal row I) likewise contains only one punch, but 011 the vertical row Z) and consequently this punch has the value on the third horizontal row 0 are two punches, namely one on the vertical row o having the value 1 and the other on the vertical row I) having the value 2; these two punches make holes simultaneously in the card, by means of which holes three units are imparted in known manner to the embroidery frame; on the fourth horizontal row cl is a punch which is located, however, in the vertical row 0, and since the punches of row 0 correspond to four units, the holes cut by them in the card also impart four times the unit motion to the embroidery frame; on the fifth horizontal row 0 are two punches a ain, namely one on the vertical row a having the value 1 and one on the vertical row 0 having the value 4 which would cause a total motion of 1+4=5 imparted to the embroidery frame by means of the card; and so on. Accordingly, it will be readily understood that the sum of the holes cut by the punches of every horizontal row a, b, c, cause displace ments of the embroidery frame which are in arithmetical progression, namely as 1 2 3 4 5 and so on.

The punches of the one drum are arranged displaced or staggered relatively to those of the other drum, so that at any time one punch of the one drum is located between two punches of the other drum. in this manner I obtain the advantage that the two drums can be arranged exactly one over the other and the punches of the bottom drum can perforate the paper at the same time as the punches of the top drum.

Each of the punches 47, 48 has a collar 49 with which the springs 50 and 51 coact tending to make the punches approach the axes of their drums and normally holding them against the cylindrical walls 52, 53 secured in the drums.

Near the ends of the drums are secured on the shafts 22 and 23 the eccentrics 54 and 55, respectively, whose straps 56 and 57, respectively, are rigidly connected together by a bar 62 and 63, respectively, and are guided by means of the parts 58 and 59, respectively, which pass through the walls of the drums, in the fixed slotted guides 60 and 61, respectively, located outside the drums, as shown in Fig. 5. At each revolution of the shafts 22, 23 the bars 62, 63 will strike against the inner ends of the punches located in the plane of the two axes of the drums and drive the same outwardly.

The illustrative embodiment comprises a device for automatically disengaging the clutch 35, 37 after every revolution of shaft 99 This device comprises a lug 64 secured to or integral with wheel 32 and a bracket shaped stop 65 secured a short distance from said lug, as clearly shown in Figs. 5, 7 and 8. hen wheel on shaft 22 has completed one revolution lug 64 coacts with the are sto sued after everv revolution of the latter.

The clutch can be thrown into gear by hand or by means of a treadle. For throwing it into gear by means of the foot I secure the treadle on the revoluble shaft 69, as shown in Fig. 7, in such manner that when the treadle is depressed shaft 69 is rotated in the direction of arrow 71. On shaft 69 is secured lever 72 pivotally connected at 7 with tie rod 74 articularly connected with rod 76 guided at 7 This rod 76 carries a pin 77 entering into slot 78 of the angle le ver 80, 81 fulcrumed at 79. lever when rotated in the direction of arrow 83 (Fig. 7) coacts with the wedgeshaped member 99 (Fig. 8) on lever 67, rocks this and throws the clutch into gear. Roller 64 then leaves the vertically clownwardly projecting part of stop 65 (Fig. and arrives between this part and wheel 32, so that this wheel can rotate freely. On the revoluble roller 84 is wound the card paper 85 which is wound up on a roller after passing over guide rollers 86, 87 and feed rollers 88, 89.

My apparatus operates as follows:-At each stitch the displacement of the pantograph pin3 (Figs. 1 and 2) is imparted to the drums 24, 25 by the toothed slides 6, 7 with the intermediary of the gear wheels 30, 31, 27 and 28, 29, 26, respectively, and rotates the same so that two definite rows of punches 48 and 49 are located opposite the rows of perforations in the plates 44, 43. Now when shaft 22 is rotated by means of the gear wheels 32 and 33 and shaft 23 is also rotated, the bars 62 and 63 are reciprocated once, the punches 47 and 48 in front of them being driven toward the plates 43 and 44, respectively. The punches 47 move in the holes 45 which guide them and enter into the holes 46 of plate 44 serving matrix. Simultaneously the punches 48 move in the holes 46 of plate 44 which guides them and enter into the holes 45 of plate 43, o that the card or paper guided between he plates is perforated. hen the shafts 2, 23 have completed one revolution the eccentric straps 56, 57 arrive into the position shown in Fig. 6, in which the bars 62, 63 have released the punches. Consequently Arm 81, of this the springs 50, 51 return the punches l? and d8, respectively, from the plates 4L3 and a l, respectively, and the drums become free for a subsequent movement.
